Installing FreePBX using custom MySQL Port get ignored by ./install script

Hi,

trying to install FreePBX using a custom mysql port get ignored (the install script always try the 3306 port):
 

./install -n --skip-install --no-ansi --dbhost=127.0.0.1 --dbport=3307 --dbuser=asterisk --dbpass=CHANGEM3 --dbname=asterisk --cdrdbname=asteriskcdrdb --webroot=/data/var/www/html --astetcdir=/data/etc/asterisk --astvarlibdir=/data/var/lib/asterisk --astagidir=/data/var/lib/asterisk/agi-bin --astspooldir=/data/var/spool/asterisk --astrundir=/var/run/asterisk --astlogdir=/data/var/log/asterisk --ampbin=/data/var/lib/asterisk/bin --ampsbin=/data/var/lib/asterisk/sbin --ampcgibin=/data/var/www/cgi-bin --ampplayback=/data/var/lib/asterisk/playback --astmoddir=/usr/lib64/asterisk/modules

Checking if SELinux is enabled...Its not (good)!
Reading /etc/asterisk/asterisk.conf...Done
Checking if Asterisk is running and we can talk to it as the 'asterisk' user...Yes. Determined Asterisk version to be: 20.2.0
Checking if NodeJS is installed and we can get a version from it...Yes. Determined NodeJS version to be: 10.24.0
Preliminary checks done. Starting FreePBX Installation
Checking if this is a new install...Yes (No /etc/freepbx.conf file detected)
Database installation checking credentials and permissions..Error!

Invalid Database Permissions. The error was: SQLSTATE[HY000] [2002] Connection refused

Of course, the MariaDB listening port is configured correctly:

1. nc -v 127.0.0.1 3306
   nc: connect to 127.0.0.1 port 3306 (tcp) failed: Connection refused

1. nc -v 127.0.0.1 3307
   Connection to 127.0.0.1 3307 port [tcp/opsession-prxy] succeeded!
   5.5.5-10.6.12-MariaDB-1:10.6.12+maria~ubu2004DjSA-Z]Dz��-��\<W~:Ay^MDO>mysql_native_password

Can be related to then missing dbport option here?

./amp_conf/htdocs/admin/libraries/extensions.class.php: return "MYSQL(Connect ".$this->connid." ".$this->dbhost." ".$this->dbuser." ".$this->dbpass." ".$this->dbname." ".$this->charset.")";

./amp_conf/htdocs/admin/libraries/extensions.class.php: return "MYSQL(Connect ".$this->connid." ".$this->dbhost." ".$this->dbuser." ".$this->dbpass." ".$this->dbname.")";

of course installing with mysql running in default 3306 port works without problems.

Thank you for the support.

Kind Regards
